1000% agree. But De Lugo is arguing against this, which makes no sense. He's complicating it.
Completely false.
It was I who started the thread, who's primary conclusion is that there's no sound reason to doubt the validity of Msgr. Lefebvre's episcopal consecration or priestly ordination (which like all consecrations and sacraments, are morally, but never infallibly, certain).
I was later bound to point out that, despite this, and contrary to the condemned position of Catharinus and Ladislaus, it is not true that the intention of the minister is certainly valid simply because he performs a rite (i.e., the condemned theory of external intention).
We presume validity in such cases, but that presumption would not be in conformity with realiy, if the minister has formed a covert contrary intention to not do what the Church does (thereby deliberately omitting a criterion defined at Trent).
This should not cause insecurity to anyone, because the power and grace of God are not constrained to the sacraments, and it is certainly not sentimental, therefore, to believe that, should we ever be so unfortunate to come under the power of wicked ministers, God would not fail to transmit grace outside the sacraments (as the quote from l' Abbe Hunter describes).
